IMPROVEMENT- INBOILERS FOR' WATER AND STEAM HEATERS.

Specification forming part of Letters Patent N 0- 173300, dated February 8, 1876 applicationfiled December 18, 1875'.

To all whom it may concern:

Be it known that I, JoHN M-. JORDAN, of the city and county of St. Louis, and State of Missouri, have invented a new and useful Im-. provement 'in Boilers for Water Heaters, which improvement is fully set forth in the following specification, reference being had to the accompanlyin g drawings.

The first part of my improvement consists in a boiler, which consists of two series of pipes lying parallel, or nearly so, with return bends, the pipes being of the same interior diameter as thepipes through which the 'Wa ter is conducted through the building to be heated.

The second part of my improvement consists in a generator, which. extends into the hotter part of the fire-chamber, as shown,so as to move the body of water before that in the rest of the boiler has attained sufficient heat to cause it to flow.

In the drawings, Figure 1 is a perspective view of the boiler proper, part of one of the outer series of pipesbein g broken away to show the propelling arrangement. Fig. 2 is a longitudinal section at a a, Fig. 3. Fig. 3 is a transverse section at b b, Fig. 2.

' A A, &c., areanumberof pipes, horizontal, or nearly so, and connected together at alternate ends, as shown, by return bends a, so as to form a continuous water-course upon one side of the furnace. vPipes B, B, and (J form a similar series upon the other side of the furnace. The return water from the building heating-pipes returns to the boiler through pipes G 0, commencing with the lower pipe of each series, A and B, and the water flows upward from the boiler through pipes E, which form continuations of the upper pipes of each series A and B. Extending forward from thelower side of each of the pipes A y and B is a' U-formed pipe, F, whose end communieates with said pipe A or B and which extends downward, so that the bend F is in near proximity to the burning fuel. The purpose of these U pipes or propellers is to cause a flow of the water through the main pipes before sufficient heat is imparted to the water to cause such flow without this device, and to cause a more rapid flow at all times.

The action of the propeller is as follows: The water in it is converted into steam, and is injected into the pipes A and B in an inclined direction, so as to communicate motion to the water in the pipes A and B The side pipes A A and B B are extended around at the rear of the furnace, as shown at A in Figs. 2 and 3.

The walling or casing G of the boiler may be of any suitable material or construction. H is the fire-grate; I, the furnace-door; J, the ash-pit door, and K the ash-pit. L is the chimney.

This boiler, being formed of separate seotions A A and B B, with separate attachments. being independent of each other, can be sensed that each section "heats a separate TOOIILOI I'OOIDS- By making the pipes throughout the whole length of the boiler and heater of the same interior diameter there is an even flow through the pipe at all parts, and no shoulders in the pipe to cause any'check to the flow. 7

It is obvious that the boiler-pipes being exactly the same interior size as the radiator and connecting-pipes, a new and quite valuable result is obtained, as the simultaneous movement of the water is insured through the Whole series of pipes at the same speed, thus preventing any eddy and dead water.

The U--formed steam water-propeller, by descending into the furnace and entering the water-pipe at an inclination, causes a circu-' lation in the water-pipes almost immediately the tire is lighted, and before the water has time to become heated in the water-pipes.

The end bends of the water-pipes, which close partially the back of the fire-space, re-

ceive the full blast of theproducts of consump tion.

The boiler, being constructed of two sepa- 1. The U-formed steam-propeller F, in

combination with the arched boiler, consisting of pipes, said propeller depending from or near the center of said arch, and inclined forward, as and for the purpose set forth.

2. The arched boiler, consisting of pipes having overlapping pipe-bends A at its rear end, as and for the purpose set forth.
